Definitions

  • the invention relates to an actuator for a motor vehicle, more specifically for a motor vehicle seat, according to the preamble of patent claim 1 .
  • Such an actuator has been known from WO 03/068551 A1 and also from U.S. Pat. No. 3,617,021 A and from WO 86/06036. Additionally, the reader is referred to U.S. Pat. No. 6,073,893 A and to U.S. Pat. No. 6,322,146 B1.
  • the invention aims at indicating an implementation of an actuator that is easy to realize in terms of construction and that comprises a zero clearance interaction, more specifically a zero clearance adjustable interaction, between the spindle nut and the spindle.
  • At least one axial socket one axial socket being preferably associated with the two axial ends of the spindle nut.
  • the axial socket is preferably made integral with the spindle nut.
  • the spindle nut may be made from metal and/or from plastic material.
  • the invention allows for a simple solution for zero clearance cooperation between the spindle nut and the spindle.
  • the elastic element urges the internal thread of the socket so far into the thread turns of the spindle that the flanks fit against each other on either side and that a zero clearance fit is achieved.
  • the functions of the spindle nut are distributed.
  • the main portion absorbs the crash forces
  • the at least one axial socket is responsible for the zero clearance fit.
  • the afore the applies in essence, for the axial socket also contributes to a certain extent to absorbing crash forces, although significantly less than the main portion.
  • the axial socket is preferably at least twice as elastically deformable in the radial direction as the main portion under the action of a radial force K.
  • the at least one axial socket is solidly connected to the main portion.
  • the two are injection-molded together or made together in another way, when made from metal, the axial socket preferably has at least one slot for it to be sufficiently elastically deformable. In principle, such type slots are also suited for other materials and configurations of the axial socket.
  • the elastic element urges the axial socket into engagement with the thread of the spindle. This is how the zero clearance fit is achieved.
  • the elastic element acts preferably over the entire circumference. It is sufficient that the axial socket is urged at one point so far into the thread turns of the spindle that a zero clearance fit is achieved there.
  • the internal thread of the axial socket is made in one work step together with the inner thread of the main portion.
  • the two threads are disposed continuously one behind the other and are continuous.
  • the axial socket has a smaller outer diameter than the main portion, more specifically an outer diameter amounting at the most to only about 80%, preferably only about 50% thereof.
  • a step that may be used for accommodating a bearing, more specifically a ball bearing.
  • the spindle nut preferably has a toothed external surface feature that is provided only in the main portion and not on the axial socket. It is thereby preferred that the external surface feature is a worm wheel.
  • FIG. 1 shows a perspective illustration of a partially sectioned actuator of the invention
  • FIG. 2 shows a perspective illustration of a combination of spindle and spindle nut similar to the configuration shown in FIG. 1 , but now with recesses;
  • FIG. 3 shows a top view of a combination shown in FIG. 2 ;
  • FIG. 4 shows an axial sectional view taken along section line IV-IV in FIG. 3 .
  • FIG. 1 shows a first exemplary embodiment and illustrates an electric motor 20 having an output shaft 22 .
  • a worm 24 which meshes a worm wheel 26 , is non-rotatably connected thereto.
  • This worm wheel 26 is part of a spindle nut 28 that engages a spindle 30 .
  • the spindle 30 is not rotated by the electric motor 20 .
  • the described parts 24 through 30 form a two-stage gearing comprising a worm gearing and a spindle gearing mechanism. The arrangement described is state of the art.
  • the spindle nut 30 has a main portion 32 that carries the worm wheel 26 on its circumference.
  • the spindle nut 28 does not differ from prior art. Still, there is a difference which is that there is provided an axial socket 34 on either of the two axial ends of the main portion 32 , the socket having an outer diameter that is significantly smaller than that of the main portion 32 .
  • the axial socket 34 is solidly connected to the main portion 32 ; in the concrete embodiment according to FIG. 1 , it is integral with the main portion 32 .
  • the main portion has in a known way an inner thread 36 that engages with the thread of the spindle 30 .
  • the axial sockets 34 each have an internal thread 38 that also cooperates with the spindle 30 and engages with the thread turns thereof.
  • the axial sockets 34 are configured to be elastic in the radial direction, meaning they can be pushed more or less onto the spindle 30 .
  • An elastic element 40 in the form of a ring-shaped spring is provided, the elastic element forming a surrounding grip around the respective associated axial socket 34 , as can be seen from the FIGS. 2 through 4 showing the second exemplary embodiment as well as from FIG. 1 .
  • This elastic element 40 abuts the axial socket 34 and pushes at least a partial portion of this axial socket 34 in such a manner against the spindle that the internal thread 38 engages the thread turns of the spindle 32 with, as far as possible, zero clearance. It forms an almost entirely surrounding grip around the axial socket 34 and also encircles the spindle 30 .
  • each unprotected portion 48 , 50 is smaller than the axial length of the protective parts 46 .
  • the arrangement is chosen such that the position of the spindle 30 shown in FIG. 1 is the central position. If the electric motor 20 is actuated in one direction of rotation, it transports the spindle 30 in one direction, it being hypothesized that it transports it leftward pursuant to arrow 52 in FIG. 1 .
  • the two protective parts 46 are retained in the position shown by a bracket 58 that is substantially configured in a U shape and forms a surrounding grip around the top of the gear housing 42 .
  • a bracket 58 that is substantially configured in a U shape and forms a surrounding grip around the top of the gear housing 42 .
  • they have a groove 60 for lateral arms of the elastic bracket 58 made from wire to engage.
  • the second exemplary embodiment shown in the FIGS. 2 through 4 is not shown completely, these figures only showing the combination of spindle nut 28 and spindle 30 as well as the protective parts 46 that are illustrated in FIG. 4 .
  • the difference from the first exemplary embodiment is that the axial socket 34 now has a recess 62 that may also be configured to be a slot, a bight portion, a hole or a notch.
  • the radial elasticity of the axial socket 34 is increased as a result thereof. It is possible to make the spindle nut 28 from metal, at least in parts from metal.
  • the axial socket 34 is quite thin, in any case significantly thinner than the main portion 32 .
  • the spindle nut is configured like a prior art spindle nut 28 , meaning it can absorb crash forces.
  • the wall is quite thin, it ranges from 1 through 3 mm, and appropriate measures have been further taken, for example material chosen, recess 62 provided and so on, for the axial sockets 34 to be at least partially sufficiently deformable for their internal thread 38 to completely mesh the thread turns of the spindle 30 without allowing axial clearance to occur.
  • the threads have oblique flanks, e.g. trapezoidal engagement.
  • the thread of the spindle nut 28 is continuous and made in the same work step, more specifically during injection molding.
  • the two protective parts 46 are built substantially according to the same principle and have more specifically the same axial length.
  • the axial length corresponds to about 65% of the axial length of the spindle nut 28 and ranges from 40 to about 80% of this axial length.
  • each protective part 46 has an abutment surface 68 by which it contacts the gear housing.
  • This abutment surface is limited either by a cylinder the cylinder axis of which passes through the centre of the spindle nut 28 and extends either parallel to the output shaft 22 or perpendicularly to the output shaft or by a ball the centre of which is in the center of the spindle nut 28 .
  • Partially cylindrical outer surfaces or ball surfaces configured accordingly and mating the abutment surfaces 68 are provided on the gear housing 22 .
  • the spindle 30 can be pivoted about this cylinder axis or about the center of the ball within a certain pivot range.
